Are you wondering whether you need a Java backend developer for your software development project? That doesn’t surprise us. After all, so many programming languages have emerged! They offer a lot. Why would you need a Java backend developer then?
Well, the truth is that Java programming language remains the preeminent choice of programming language for software development. That’s true for server-side programming too.
What makes Java so popular for backend development? What should you do to hire a competent Java developer? How should you go about this hiring process? Read on, as we explain it all in this guide.
Java: The programming language of choice for backend development
The powerful features of Java offer plenty of advantages when you develop APIs and web services. Beyond REST APIs, Java can help you with developing microservices. This programming language can help with scripting and developing algorithms too.
Coders continue to prefer Java for web development. Java retains its importance in native Android development also. Programmers prefer it due to the following reasons:
1. General-purpose language
Java remains an excellent choice for a wide range of development projects. You can use it for web development, mobile development, network programming, etc.
2. The ease of learning path
Java utilizes the fundamental principles of programming very well. The syntax is easy to learn, and programmers can learn it quickly.
3. Cross-platform language
You can write a Java program, compile it, and run it on all major platforms. Any platform that supports the “Java Virtual Machine” (JVM) can execute Java programs. You can run Java programs on Windows, Mac, Linux, Android, etc. You can use Java for database connectivity.

Java supports multi-threaded processes, which is advantageous for CPU-intensive applications.
Java offers significant security features. To start with, it’s a statically-typed language. This prevents variable type-related defects by design. Java employs useful security-related algorithms, protocols, and mechanisms.
Java APIs support its security features. These APIs include authentication, secure communication, access control, PKI (public key infrastructure), and cryptography.
6. Java libraries
Programmers can use a variety of Java open-source libraries. These make many common tasks like JSON-parsing, XML-parsing, HTML-parsing, messaging, logging, etc. easier. A web developer working on the backend part will find this rich collection of libraries especially useful.
Java supports automatic memory management and garbage collection. These help developers code scalable apps.
Java has excellent development frameworks, and these support backend development considerably. Developers can use the Spring Boot framework, Grails, Hibernate, Apache Struts, and many other useful frameworks.
9. Tooling support
A software engineer will find it easy to code using Java since it has excellent tooling support. Developers can use the Eclipse IDE. They can also use other useful tools like NetBeans, Jenkins, Maven, etc.
Hiring a Java backend developer: The choice of hiring platform
You are likely wondering about hiring platforms when hiring software engineers with Java skills. Choose between one of the following options:
1. Freelance platforms
Freelance platforms can help you to hire a Java programmer. Some of these platforms have large networks of freelancers, therefore, you will likely receive many applications.
A few freelance platforms claim to use a stringent vetting process. They claim to connect you to high-quality developers only. Finally, you might be able to negotiate a low hourly rate.
You need to keep the following disadvantages in mind though:
- The lack of management support: Freelance platforms don’t offer management support. You will need to manage the work of freelancers, who might work remotely.
- Part-time developers: Freelancers typically work part-time on a project. This might adversely impact your project schedule.
- Turnover: Freelancers look for better opportunities to earn. They might leave your project mid-way if they find such an opportunity. You need to find a software developer to replace the freelancer.
- Uncertainties: If you have a complex project, then you would like to reduce other complexities. You can’t do that with part-time freelancers working remotely.
2. Job boards
You can post Java developer jobs on various popular job boards. These job boards can increase the visibility of your job postings, and many candidates might apply. That’s an advantage.

You need to interview the shortlisted candidates. Once you select a software engineer, you need to manage the hiring process. Remember that job boards don’t offer any project management support.
You need to contend with the following risks:
- High management effort: You own the entire hiring and contracting process. You also manage the work done by the developer.
- Turnover: You need to find a replacement if the developer leaves the project mid-way.
- Hiring lead-time: You might need to post your jobs on many job boards to gain appropriate visibility. This involves quite a bit of effort, and your hiring lead time may be high.
- Uncertainties: While you might assess the technical skills of the shortlisted candidates, assessing their competencies can be hard. E.g., will the developer work collaboratively with your larger team?
3. Software development companies
Software development companies can help you to hire Java developers. Do you have a complex project? You might want to hire a developer from a software development company since it offers the following advantages:
- Ease of hiring: These companies offer a simple hiring process. You will find the processes like contracting, billing, etc., easy.
- Management support: Software development companies provide management support. They typically assign a dedicated account manager. The account manager provides management oversight for their developers, which helps.
- High-quality developers: Software development companies regularly encourage their developers to upskill themselves. This also makes the developers more motivated.
- Mitigates uncertainties: You get full-time developers. In case a programmer leaves in the middle of a project, a software development company will provide you with a replacement.
Creating a job posting for a Java backend developer position
After choosing a hiring platform, you need to create a job posting. Include the following in that:
1. An introduction to your company
Provide a brief introduction to your company so that the prospective developers know enough about it. Make this introduction informative. Remember to make it exciting too.
Explain the career development opportunities you offer. Provide details about the working environment, work culture, and the potential for growth. Explain the compensations and benefits that you offer.
2. The job description
Describe the position briefly. Talk about the kind of projects that the developer will work on. Mention whether the programmer will work on development as well as maintenance projects. Explain the importance of these projects, and talk about how they matter to the organization.
3. The job responsibilities
Explain the job responsibilities of the Java developer. These should include the following:
- Understanding the business requirements by working closely with the business analysts or business stakeholders;
- Studying the technical solutions by collaborating with the architect;
- Creating program specifications;
